To all whom it may concern. 5

Be it known that I, EDWARD =HORNBY Fos'rnR, a subject of the -King ofGreat Britain, residing at Queensbury, Bradford, in the county of York,England, have invented certain new and useful Improvements Relating toSpinning and Analogous Machines, of which the following is aspecification.

This invention relates to spinning and analogous machines, moreparticularly to dofling mechanism therefor-,and it has for primaryobject an arrangement whereby eX- isting spinning and like frames may beprovided with mechanical dotting means without necessitating structuralalterations and consequently. without impairing the rigidity of theframes or the stability of the spindles.

The inventionalso has for object to effect certain improvements in themechanism whereby in so far as flierspinning frames are concerned theliability of the yarns or threads to become detached from the fliersduring the dofling operation is eliminated.

According to the'invention, the dofiing elements, that is to say, themeans for removing the fliers or caps, as the case may be, and the meansfor the reception of thefull and empty bobbins respectively, are mountedupon a frame or carriage which is adapted to be attached to the front ofthe spinning machine and which is arranged so as to be traveled"vertically of same. The spindle rail is not traveled in order to effectremoval or replacement of the bobbins but the bobbins are movedrelatively to the spindles by means of the lifter-plate. I Theaforesaid, frame or carriage is carried theupper extremities of verticalpillars passingthrough guides which may be bolted to the main frame ofthe machine and said carriage, or the pillars, is, or are, connected bysuitablemeans for raising and lowering same. Upon said carriage thereare mounted a series of angularly movable wires or bobbin-setters forthe reception of empty bobbins, a series ofholders to remove the fliersor caps, as the case may be, from the spindles, ,a series of carrierdevices for. the transfer of fullbobbins which devices are provided withautomatically op erating retaining and releasing means for thebobbinsthereupon, and a series of pegs for thereception of the full bobbinsfrom off the transfer carrier devices.

The series of holders and the series of transfer carrier devices areadapted to. be reciprocated, independently in horizontal planes in orderthat each may be positioned to perform the requisite functions, and inthe case of a flier spinning frame the flier holders are combined withmeans for the reception of the eyes of the fliers so as to preventdisengagement of the thread therefrom. 1

The aforesaid carrier, devices serving to transfer the full bobbins fromthe spindles may consist of a series of pegs which take into the boresof the bobbins as they are removed from thespindles, or, instead ofpegs, the devices may consist of clips which are adapted to grip thefull bobbins externally.

he accompanying drawings illustrate by way of example the application ofthe invention to a flier spinning machine of a known and usual type.

: Figure 1 is a front elevation of a portion of the machine taken atsay, the right hand end of same, only one spindle being shown complete.Fig. 2 is an end elevation of the same end of the machine the mechanismat one side only of the machine being shown. Figs. 3 to 10 inclusive areall end elevations of so much of the end-stand as is necessary toillustrate the spindle and the dofling elements, and these figures showthe positions occupied by the several parts during the successive stagesof the doffing. operation. Fig. 11 1s a sectional elevation showing thedofling elements in the normally retracted or inoperative position; andFig. 12 is a similar elevation showing the same elements in the forwardor operative position; it being understood however that all theseelements are not positioned simultaneously as shown in the figure. Fig.13 is a front elevation'of a flier holder which may be employed, andwhich is also included in the otherlviews. Fig. la is a. detail view ofmechanism for rotating the spindles manually. Fig. 15 is a sideelevation showing the drive to the lifter plate; Fig. 16 1s a frontelevation of same with certain parts omitted. -F ig. 17 'is a frontelevation of the mechanism for raising and lowering the carriagecarrying the doffing elements.

Referring to Figs. 1 and 2, 1 is a carriage mounted at the upper ends ofvertical pillars 2 which are adapted to slide in suitably.

shapedguides' 3 each carried bya bracket 4 bolted to the endstand 5andto inter1nedi 1 ate frame members 6. In Fig. 2 the bracket 4. is notshown bolted to. the endstand as in Fig. 1 but is omitted for the sakeof clearness.

The bottom of the carriage 1 consists of a rail running longitudinallyof the front of the machine and to this rail are secured end plates andintermediate plates 7 which serve to carry in bearings theseveral shaftsor rods which are employed for the manipulation of the dofiing elements;

The carriage 1 is adapted'to be traveled vertically in front of thespindles, and to this end it is connected to mechanism for operatingsame. This mechanism may con- 'sist; when the'operation is to beeffected 1 manually, of a handwheel 8 mounted upon a shaft 9 upon whicha sprocket wheel 10 is keyed, which sprocket wheel is connected byachain 11 to a sprocket wheel 12' carried by a shaft 13 upon which shaftapinion 14 @1 6 k y d. This pinion 14 meshes, with a pinion 15 carriedby a shaft 16 uponwhich isalso mounted a pinion 17 which meshes w1th apinion 18 keyed upon a cam shaft 1 19, provided with a cam 20.

'Mounted upon a rock shaft 21 at the bottom'of the frame of the machineis a lever 22 having integral therewith an upwardly extending -arm23 atthe extremity of which is a freelyrotating roller 24 adapted to con tactwith the peripheryoffthe cam 20.

The forward extremity of thelever 22 is bent upwardly and is coupled tothe carriage 1 by means of a connecting'link 25 pivoted at itslower endto said lever 22' and at its upper end to a short link 26 which is1111311111 pivoted to the underside of 'theca'rriage 1.

The rock shaft 21 extends along the en-- tire length of the machine andthe connections between the carriage and'same may be multiplied as m ybe 7 demanded the length of the machine.

At its inner or rear extremity the lever 22 carries a balance weight 27to counterbalancethe carriage, 1 in its upward and downward travela 28is the usual tin cylinder for the driving tapes .and it is mounted uponthe shaft 29 which is adaptedto berotated by means of the usual drivingmechanism.

each spindle 30 beingprovided with the usual whirl 32 and with a flier33 which is 1 adapted to -screw on to the upper end of the spindle.

34 is the lifter plate which functions 1n theusual manner and which isalso utilized for the purpose of removing the full bobbins from thespindles in a manner hereinafter described. 1

35 is the thread board which is hinged to the'beam 36 and is adapted'tobe raised by a means of cords or wires (not shown) connecting same to 'ashaft 37 having an operating lever 38, for the purpose of providingroom'for the doiiing elements when raised to their uppermost position asexplained here'- after.

rolls. 7 a r Beforethe dofling takes place all the fliers 33 must bepositioned squarely of the front ofthe machine in order'that when thehold- 39 an d 40 are the usual drawingfdown ers to remove same areoperated the fliers may be all arranged symmetrically and "cafpable-ofbeing seized,'and in addition to this all the-fliers mustbe unscrewedfrom the spindles. For this purpose means are pm I vided for rotatingthe spindles 'and means are also provided for holding the fliers againstrotation at the same time.

The means for rotatingthe spindles are illustrated in detail inFigQ'14;and comprise hand eel 41 carried by a short shaft 42 mounted in abearing 43 bolted to the endstand 5, said shaft 42 havingkeyed to it apinion 44 meshing with a pinion 45 keyed to a shaft 46 which extends theentire length of the machine behind the spindles 30,

a-nd which has secured upon it, in rear .of each'spindle 30, a skewfgearwheel 47 which meshes with a corresponding gear wheel 48 formed on orattached to the spindle 30.

The means for positioning all the fliers 33 and for holding same againstrotation when the spindles 30 are turned comprise a hori zontalrookshaft 49 carried in'suitable bearings upon the frame ofthemachine'andhaving fixedto it a number of fingers b O each of which is adapteditobef'moved anguilarly into the path of rotation of its corre spondingflier by therock-shaft 49 being turned by means of an operating handle Ith o a 1 1 1 1 The meansfor effectingjthe removal of the full bobbinsfrom the spindles and the substitution therefor'of a supply of emptybobbins will now be described;

The carriage lhasarranged upon it'yin suitable bearings, a;longitudinalrod or shaft 52 whichis capable of beingmoved angu larly bymeans pf a hand wheel 53,lever or the like,"'al'nd which is fitted withaseries of wires 5d orbobbinsett'ers of known form, one opposite eachspindle, which wires are adapted to be moved angularly and positionedaxially over the Spindles 30to place thereon a series ofeemp'ty bobbins,the car riage 1 being raised to a convenient height for this purpose asexplained hereaften Also arranged upon said carriage 1 are twolongitudinal bars 55, 56' (see especially Figs. 11 and 12) parallelwithone another, whereof the .upperbar 55 hasattached to it a series ofholders 57 for the fliers 33, and the lower bar 56-has attached to it aseries of transfer bobbin pegs-58 to receive fullbobbins from oflthespindles30.

The flier holders 57 are pivoted tothe bar 55 and project horizontallytoward the spindles"; each being provided with an adjusting screw 59beari ng on the bar 55 and a locknut 60, and each holder 5,7is formed atitsforward extremity with a bifurcation 61 (see Fig. 13) to receive theneck of the flier 33 and with a pair of hook-shaped lugs 62, 62,depending below said bifurcated f0rward extremity 'toI receive andretain the top" bar of the flier. Further, each flier holder 57' may beprovidedat itsforward extremity with an attachment depending below sameandfcomprising aninverted U- shaped member 68 whereof thevlowerextremityof each limb isfashion'ed with a boot or ring 64: lto receivethe eyes of the flier when the latter is in place on the holder, saidboots or rings being prefer ably linedwithfelt or other analogousresilient material. i

The transfer bobbin pegs 58 are attached by their upper ends toforwardly projecting plates or fingers 65 secured by screws 66, 66, toabar5'6, and each of said pe 's 58is provided with a self-acting clip 67hinged or otherwise attached at 68 theretoand whereby theb'obbinis'retained thereon, each of said clips 67 beingfashioned with adepending trigger portion 69 controlled by a spring 0 so as to cause theclip 67 to grip the bobbin against the peg 58; i I 1 :The ends of thebars 55, 56' are supported in grooves or slots 71, 72, respectivelyformed in the end plates 7 and said'bars are respectively providedwithrack surfaces 78and 74 engaged respectively by pinions 75, and 76mounted upon shafts 77 and 78 carrying operating. hand levers 79 and'SOwhereby said'bars are traveled to project the holders 57 andthe p'egs58'towardthe fliers '33 and spindles '30 and to retract same therefrom; fBelow the carriage 1,:and attachedthereto, by means of hangers81 or tothe pillars 2 supporting same, is a longitudinal bar 82 carrying a rowof upstanding receiver pegs 8 3 destined to receive the full bobbinswhen the latter are released by the clips 67 from the transferpegs 58;or instead of being carried by a continuous bar 82 groups of say twelvepegs 83 may be carried by independentlengths of such bar, as shown, eachof which lengths (or the whole bar if continuous) is connected to thecarriage 1 or its other supporting means by a parallel linkage 84 aswill be'well understood without" special illustration, whereby thereceiver pegs 83 with the full bobbins thereon may be drawn outwardly ofthe carriage and of thedofling elements thereon, thus admitting of theunobstructed removal of the full bobbins by hand from OH said pegs. Thenormal position of the carriage 1 during the operation of spinning issome distance below the level of the fliers 38, and during said spinningoperation a series of empty bobbins are placed by hand upon theangul'arly movable bobbin setters or wires 54: in readiness to be placedon to the spindles 30 when the full bobbins have been removed therefrom.

During the operation of dofling,-the carriage l is caused automatically:to assume the requisite verticalposition which come sponds with theparticular step in the operation to be performed, by means of thefollowing mechanism: A lever 84 is pivoted to across member 85 of themain frame of the machine, and the free end of this lever engages with aslotted disk 86 which is keyed upon the shaft 19 (see Figs. 1 and 17).This lever'84is connected by means of a link 86'to a clutch for 87'which engages one member 88 of a serrated or dog clutch, said memberSSbeing mounted so as to rotate with and to slide freely on the shaft 13upon which shaft the other member 88 of the clutch is keyed fast. A footpedal (not shown) is providedin order to disengage the lever 84- fromthe disk 86 when required.

Referring to Figs. 15 and 16, 89 and 90 i are the fast and loose maindriving pulleys, below which in Fig. 15 is shown the mechanism forcommunicating the larger up .and down motion to the lifterplate'34required, besides the usual mechanism for providing the usual up anddown motion. This mechanism consists of the usual cam 91 carried by ashaft 92 and contacting with a roller 93 on a pivoted arm 94 whereof theupper end isconnected as usual by a chain to the lifter plate, which,because of its length,

does :not interfere with the normalup, and u down operation of thelifter plate 34cfrom 'tl'ie shaft 29. The shaft 92-is driven=by means ofskew gear 95, 96 actuatedby chain and sprocket mechanism 97, 98' fromshaft hingedfrontportion of thethread board 35 dles; and-qthisis done byturning. shaft 49 19. W'heni'the 'machine is in normal operation,-the;wholeof the driving mechanism for shaft 19 is out of operation.

' Instead of the hand wheel 8 on the shaft 9,,the said shaftv may bepower driven by means of suitably controlled connections from the'loosepulley 90. Y

The operationiof the apparatusduring theprocess of dofling will now bedescribed.

the spindles are completely filled with Assuming that the series ofbobbins upon thread, and are therefore in a condition to be doffed, themachine is stopped by throwing the driving belt over from the pulley 89to the pulley 90 in the usual manner, and the is raised angularly upward(as in Figs. 3 to 9) by turning hand lever 38-and shaft 37,

thus removing any obstruction which the thread board might offer to .theraising of the carriage 1 and the doffing elements thereon. Havingremoved the belt from the driving pulley '89 the spindles 30 are free tobe turned by hand to position all the fliers 33 and to unscrew same fromthe spinby means of handwheel 511 so -as to raise the fingers '50.angularly upward intothe position indicated by dot-and-dash lines inFig. 2,' when they are then projected into the'paths of rotation oftheir respective 46 in an endwise direction, thereby disengaging theworm wheels 47 from the worms 48, the motion of the shaft 46 for thispurpose being communicated from the shaft 42 by the shrouded gear wheel44 which 00- operates with the gear 45. When the fliers have thus beenunscrewed and are resting freely upon the plain upper portions of thespindles, the fingers 50 are lowered and the carriage 1 is raised intoits first position to bring all the bifurcated flier holders 57 to apoint level with and in front of the top bars of the fliers. Thisraising of .the carriage liis effected by turning hand, wheel 8 andshaft 9 the rotary motion of which is transmitted by the chain andsprocket, mecha: nism 10, 11, 12 to the train of gearing 14,

'15, 17 and 18 and thereby to the shaft 19 and the slotted disk 86; thecarriage being arrested automatically on arriving at. the correctheightby the lever 84 engaging with the appropriate slot on theperiphery of the disk 86 and theupward travel of the carriage beingcaused by the rotation of the cam .20 the configuration of theperipheryof which causes the armw23 and hence also the lever 22 to be movedangularly and the link 25 tobe-moved upwardly. The passing of the lever84 into the slotted disk causes the'clutch member 88 to be disengagedfrom the clutch member 88?,and the carriage is thus operativelydisconnected for the time being. Upon the arrival of the carriage 1 atsaid first-position the flier holders 57 are advanced until theirbifurcated front extremities engage the fliers (as in F ig.. 3), suchadvancing of saidflier vholders being efiected by turning shaft 77 byhand lever 79 causing the rack and pinion mechanism 7 3, 75 totravel thebar toward the spindles. If desired theoperationof unscrewing the flierscan be delayed until after, the fliers have been. seized. Whenthefliers33 have thus been engaged by the flier holders its secondposition, where it is automatically arrestedas before, and when thebobbin 1 pegs 58 are sufliciently high to enable them to beadvanced-into position co-axially with and above the tops'of thespindles 30. As the carriagel is being raised, thefliers 33 are engagedby the hook-shaped lugs .62, 62, on the flier holders and the eye ofeach flier enters theieorresponding felt. lined .boot or ring 64011 themember 63 in which said eye is retained in such amanner that the threadcannot become disengaged therefrom during the further manipulation of Ithe fliers. Fig. 4 shows the carriage raised sufficiently to carry thefliers 33 clear of the tops of the spindles, after which the bar 55 isretracted, carrying the fliers back also into the position shown inFig.. 5 WhlCl1 figure also shows thebobbin pegs 58 in place above thetops of the spindles. The bobbin pegs 58 are advanced toward and overthe spindles by turning shaft 78 by means of hand lever 80 causing thebar .56. to be slid toward 7 the spindles by means .of the rackandpinion mechanism 74, and 76. r The handwheel; 8 is then turned untilanother slot on the disk 86 is entered by the lever 84, during which,rotationof the hand wheel 8 the rentran't portion of the cam 20 orthatI portion ofthe peripherywhich is of'lesser radius than the remainder is=engaging the roller 24 on arm 23 to which arm therefore 'no angularmovement. is, imparted and the carriage is consequently stationary. Theturning-of the shaft19, however, rotates the lifter cam 91 throughgearing 95, 9 6, 97iand 98, raising .the lifter plate 3% and inconseuenceIbfecauseof its greater throw, over; the normaland usualoperation of the mechanism controlling the lifter plate, slidingthefull} bobbins Fgupwardly, of the spindles 30 and as same on to thebobbin pegs 58 as shown; in Fig. 6.; As 1 each full bobbin F approachesthe upper end ofthe; peg 58 it engages the hinged clip 57 which itforces outward and whereby it is securely held by pressure against itsperiphery. The bar 56 is then retractedto its original position by theoperating hand lever 80, in which position the pegs 58 are coaxiallyabove the receiver pegs 83, and shortly before the limit of the backwardmovement of said bar 56 is reached the spring controlled dependingtrigger portion 69 of each clip 57 abuts against the rock shaft 78causing the pressure of the clips 57 upon the full bobbins F to bereleased automatically and permitting said full bobbins to slide off thepegs 58 on to the receiver pegs 83 below, as shown in Fig. 7. The lifterplate 3% is then lowered by reversing the operation already describedfor raising it, and the carriage l is also lowered until again arrestedby the lever 84: and disk 86, in which position the Wires or bobbinsetters 54 may be moved angularly toward and into co-axial alinementwith the tops of the spindles. As already stated, these wires or bobbinsetters 54 carry a supply of empty bobbins E, and they are positionedover the spindles 30 by turning the rockshaft 52 toward the spindles bymeans of hand lever 53 so that the empty bobbins E slide freely off thewires 54 on to the spindles 30. The carriage l is then adjusted to aheight suitable to allow the fliers 33 to be replaced over the spindles80 which is efl'ected by reversing the operation already described forremoving the fliers. Fig. 8 shows the fliers advanced once more abovethe spindles on which they are then replaced and after the holders 57have been withdrawn into the position shown in Fig. 9 the fliers arescrewed on by once more raising the fingers 50 and turning the spindles.The carriage 1 is then once more adjusted to a suitable height to enablea few turns of the thread to be placed on to the empty bobbins E whichis effected by continuing to turn the hand wheel 41; and the threadsextending between the empty bobbins E and the full bobbins F are thensevered by an angularly movable cutter bar C of known form. After thethreads have been severed the carriage 1 is lowered to the normalposition of rest, the thread board is lowered into position (see Fig.10) and the machine is re-started. The groups of receiver pegs 83 arethen drawn out by their parallel linkages into the position shown indotted lines in Fig. 10 and the full bobbins to a flier spinningv framehaving been selected merely by way of example. It' will also be obviousthat owing to the special design and simplicity of operation of themechanism it can be adapted with great facility to existing spinningframes without necessitating structural alterations of any importanceand without impairing the rigidity of the frames or the stability of thespindles.
